MEASURING DEVICE.

Application filed November 13, 1928.

In the walnut industry it is customary to subject the hulled nuts to a bleaching bath in the process of preparing them for the market. It has been found that the best and most uniform results can be obtained by injecting into the bath at frequent and regular intervals fresh quantities of the bleaching liquid. T he bleaching liquid commonly used comprises an acid and an alkali in the proportions, preferably oi one to ten.

It has heretofore been the custom to leave the measuring of the two liquids to the judgment of the operator with the result tiat a uniform bleach could not be secured.

It is the object of the present invention to provide a means whereby predetermined quantities of the desired bleaching liquids can be measured separately and mixed only upon their discharge from the measuring de vice, the mixing of the liquids at the moment of use being desirable to secure the most efficient results.

In the drawing:

Figure 1 is a side elevation of a device embodying my invention.

Figure 2 is a plan View of the same.

Referring more particularly to the drawing, I show at 1 a suitable standard having bearings 2 mounted thereon; the bearings 52 having a shaft 3 mounted therein.

On the rock-shaft 3 is mounted a receptacle 4 having two large liquid holding chambers 5 and 6 formed therein as shown, these chambers being of equal size and divided by a partition 7. In elevation the receptacle shows a symmetrical figure with its bottom forming an obtuse angle and its top'an oppositely directed obtuse angle the apex of which centers on the outer end of partition 7 On the upper end of support 1 are arranged oppositely directed stops 8 and 9, these stops being positioned under the bottom of receptacle 1 at its center. The stops 8 and 9 have diverging upper surfaces as at 10 and 11, and the angularity of these surfaces is such that when one of the charm bers 5 or 6 is in a vertical receiving position the bottom of the other chamber rests on the stop underneath.

As clearly shown in Figure 1 this construction and mounting of the receptacle 4 imbalances it so that it will normally rest Serial No. 148,228.

either in the position shown in solid lines with the chamber 6 in a receiving position or in the position shown in broken lines with the chamber 5 in a receiving position.

On the side of receptacle l and identical in form and arrangement therewith, is a second receptacle 12. This receptacle, however, is smaller in size and in the present case the chambers therein are proportioned to hold one tenth as much liquid as the larger chambers. The smaller receptacle is indicated at 12 with the two chambers at 13 and lldivided by partition 15.

it 16 is shown a tank from which the larger chambers are filled by means of a pipe 1? controlled by a valve 18. At 19 is shown a tank from which the smaller chambers are filled by means of a. pipe 20 controlled by a valve 21.

Assuming the device to have been constructed and assembled as above set forth with the larger tank 16 filled with a suitable lime solution and the smaller tank 19 tilled with a suitable acid such as sulphuric.

The controlling valves 18 and 21 are now operated until the chambers 6 and 14 are filled at the same time. The additional weight of the liquid in these chambers now overbalances the receptacles and they drop to the position shown in dotted lines and simultaneously discharge their contents, at the same time throwing the chambers 5 and 18 in receiving positions. hen these two chambers are filled they automatically empty themselves and return the chambers 6 and 14 to receiving positions.

It may now be readily seen from the foregoing that I have provided a device that is simple in construction, positive in operation, accurately measures the desired liquids in their proper proportions, and is entirely automatic, being operated entirely by the liquids to be measured.

It is to be understood, of course, that while I have herein shown and described but one specific embodiment of the invention, changes in form, construction, and method of operation may be made within the scope of the appended claim.

I claim A device of the character described, com sing a standard, a rock-sh ft mounted een and stops mounted sea on either side of said shaft, and a receptacle mounted to swing on said shaft to alternately engage said stops, said receptacle comprising a single integrally formed element, the bottom forming an obtuse angle and its top an oppositely directed obtuse angle, and having two pairs of chambers of unequal capaci- JOSEPH A.
